The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

In the key study, after 28 days, the mean of degradabilities by BOD measurement was 85%, the mean of degradabilities by DOC measurement was 96%, and all of the disappearance rates of the test substance were more than or equal to 98%, all leading to the judgment that the test substance is readily biodegradable (Mitsubishi Chemical Safety Institute, 2001).

A Pseudomonas sp. strain was isolated by enrichment culture from soil using 2,3-dichloro-propanol-1 as the sole carbon source.

> 99 % degradation occured after 24 hours. Therefore the substance is considered readily biodegradable (Castro, C.E. & Bartnicki, E.W., 1968).

In one strain, an inducible epoxide hydrase using glycidol as substrate was detected in 40000 g crude supernatants from bacterial extracts. Enzyme activity (30 degree C, pH 7.5, 5 mM glycidol):  bacteria grown on epichlorohydrin 107 U/ g prot., grown on glycidol 817 U/g prot.Glycerol was identified as hydrolysis product (van den Wijngaard, A.J. et al., J., 1989).

Therefore, 2,3-epoxypropan-1-ol is considered to be readily biodegradable.
